All-season floating blanket

Abstract

Bed covers (20) which can be elevated above a bed (50) solely as a result of differential air pressure. A small blower unit (80) located under the bed (50) supplies air to an air-flow channel network (22) making up the central portion of the bed covers (20). The air-flow channel network (22) is made up of fabric layers which are joined along selective linear alignments (46 and 48) to produce air flow channels (40, 42, and 44). The upper (24) and middle (28) fabric layers are less permeable to air flow than the lower layer (32). The air flows from the blower (80) through a conduit (82) into the air-flow channel network (22), throughout the network (22), and thence through the bottom fabric layer (32). The uniform distribution of air through the bottom layer (32) creates a region of higher pressure under the bed covers (20), thus causing the formation of a cavity (60) between the bed covers (20) and the bed (50).

I claim: 
     
       1. A bed covering system comprising a bed cover which can be elevated above a bed comprising a mattress and a box spring, thus creating a cavity between the bed cover and the bed, said cavity being formed as a result of higher air pressure within the cavity as compared to the air pressure outside the cavity, comprising: (a) upper and lower fabric layers defining channels therebetween, said layers selectively connected together to form an air transportation and distribution network, wherein air is transported through the channels of said network and thence through the lower fabric layer, thus creating the higher air pressure under the bed cover as compared to the air pressure above the bed cover, the cavity being of a sufficient size to substantially enclose the user(s) of the cover, the lower fabric layer of the cover, having peripheral extensions adapted to be tucked between the mattress and the box spring supporting said mattress, the lower fabric layer including an opening closable by fastening means, said opening adapted to permit the user's entry into, and exit from the cavity,   (b) an air blower, and   (c) means for connecting said air transportation and distribution network to said blower.
